The game uses a central drinking glass and a coin, its really easy and fun.

Each player takes it in turns. On their turn, they put any amount of their own drink they choose into the central drinking glass (the 'Dirty Pint'). They then must toss a coin, calling which side they predict it will land on.

If they choose correctly, then the Dirty Pint is passed to the next player. He/she then adds their chosen amount and then tosses then coin themselves.

If they choose incorrectly, they must down whatever is in the Dirty Pint at that time.

Contestants grip a 2p piece between their cheeks and then walk/waddle to pint pot, stand over it and release 2p in to pot. Organise in to two teams etc Especially good when girls are joining in and need help with initial positioning of 2p

WhoDat. One bottle of spirits or slab of tinnies each, to be consumed between dits. When bottles/cans are all empty, one person leaves the room and the other must guess who that was before falling asleep.

For Larger groups:

A good fallback option is the timeless Spoof. No cards are needed, it just needs a little alertness/guile and the drinking can be paced. (Some Scotsmen may find difficulties as it involves both coins AND pockets)
